• Open GL ES 2.0 co-ordinate systems

  - by Chris

  Hi, I want to use Open GL ES 2.0 for a new game, but I have two questions. Q: The first is how do I set up perspective views in Open GL ES 2.0 - do I need to include Open GL ES 1.0 and use glOrtho, or is there a new way? Q: I want to use the 4th quadrant of a Cartesian co-ordinate system for my game and not use -0.5 to +0.5 for values on screen, how once the first question is answered can I achieve this?

• simply way to add another webapp framework to my project.

  - by zjm1126

  one webapp project has many url and i have to change this: ('/addTopic', AddTopic), ('/delTopic', DeleteTopic), ('/addPost', AddPost), ('/delPost', DeletePost), to this: ('/tribes/addTopic', AddTopic), ('/tribes/delTopic', DeleteTopic), ('/tribes/addPost', AddPost), ('/tribes/delPost', DeletePost), but ,if i add this to my project ,i have to change the url in every py file or html file , in django it can be this : urlpatterns = patterns('', (r'^articles/2003/$', 'news.views.special_case_2003')), ) it is easy to add the url of 'news' to my peoject, but does webapp has this ? thanks updated: (1) my main page url is : ('/', MainPage), ('/sign', Guestbook), (2) the url of a webapp project that i want to add is : ('/', MainPage), ('/logout', LogoutPage), ('/login_response', LoginHandler), and i want to change (1) to this: ('/', MainPage), ('/sign', Guestbook), ('/aa/', p2.MainPage), ('/aa/logout', p2.LogoutPage), ('/aa/login_response', p2.LoginHandler), so i have to change so many url like / to /aa/ , or change /logout to /aa/logout in py file and html file , that is a hard work so any simple way to do this ?

• What tools are people using to measure SQL Server database performance?

  - by Paul McLoughlin

  I've experimented with a number of techniques for monitoring the health of our SQL Servers, ranging from using the Management Data Warehouse functionality built into SQL Server 2008, through other commercial products such as Confio Ignite 8 and also of course rolling my own solution using perfmon, performance counters and collecting of various information from the dynamic management views and functions. What I am finding is that whilst each of these approaches has its own associated strengths, they all have associated weaknesses too. I feel that to actually get people within the organisation to take the monitoring of SQL Server performance seriously whatever solution we roll out has to be very simple and quick to use, must provide some form of a dashboard, and the act of monitoring must have minimal impact on the production databases (and perhaps even more importantly, it must be possible to prove that this is the case). So I'm interested to hear what others are using for this task? Any recommendations?

• ASP.Net MVC elegant UI and ModelBinder authorization

  - by SDReyes

  We know authorization stuff is a cross cutting concern, and we do anything we could to avoid merge business logic in our views. But I still not found an elegant way to filter UI components (e.g. widgets, form elements, tables, etc) using the current user roles without contaminate the view with business logic. same applies for model binding. Example Form: Product Creation Fields: Name Price Discount Roles: Role Administrator Is allowed to see and modify the Name field Is allowed to see and modify the Price field Is allowed to see and modify the Discount Role Administrator assistant Is allowed to see and modify the Name Is allowed to see and modify the Price Fields shown in each role are different, and model binding needs to ignore the discount field for 'Administrator assistant' role. How would you do it?

• Django, CSRF protection and js generated form

  - by Neewok

  I have to create a form dynamically via javascript (yeah, that sounds ugly, but read this for the reason) and wants to make its submission CSRF proof. Usually, I use the @csrf_protect decorator in my views, and the {% csrf_token %} tag in my templates, as recommanded in the doc. But what should I do with a client-side generated form ? If I add a '/get_token/' view to generate a token on the server and obtain its value (say, via JSONP), then that means that I'm creating a backdoor an attacker could use to bypass the protection. Kinda head-scratching. What would you recommand ?

• MVC MapPageRoute and ActionLink

  - by Dismissile

  I have created a page route so I can integrate my MVC application with a few WebForms pages that exist in my project: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); // register the report routes routes.MapPageRoute("ReportTest", "reports/test", "~/WebForms/Test.aspx" ); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); } This has created a problem whenever I use Html.ActionLink in my Views: <%: Html.ActionLink("Home", "Index", "Home") %> When I load the page in the browser the link appears like: http://localhost:12345/reports/test?action=Index&controller=Home Has anyone run into this before? How can I fix this?

• What was the most surprising failure of your 'Engineer's intuition'?

  - by Bubba88

  Hi! This may seem as an open-ended question but I'll surely accept the most impressive and upvoted answer ;) Basically, I could describe my own case - I just fail 5 times a day with my intuition cause very frequently I can be just not up-to-the-speed with my requirements/manager/team/etc. and I just have to make code quickly - that's why proper formalization in many cases stands aside. I want to gather some experience of yours - what was the most epic failure when you did rely on you implicit reasoning/intuitive knowledge/immediate perception etc. of course everything you describe should be related to programming/computers. It's mostly just to measure the danger of using that 'it's obvious..' words. I've made it com. wiki to be properly transformed after gathering enough views count. Thank you!

• Rails override validator message

  - by Anand

  Hi, I have a site thats served in 2 flavours, English and French. Here's some code app/views/user/register.html.erb ----------------- <% form_for .....> <%= f.text_field :first_name %> <% end %> app/models/user.rb ------------------ class User < ActiveRecord::Base validates_presence_of :first_name end Now to display the error message in case if the site is being served in the French version, I have app/config/locales/fr.yml ------------------------- activerecord: errors: messages: empty: "ne peut pas être vide" So if someone does not fill in a first name, the validator takes the name of the field and appends the custom message for empty clause giving "First name ne peut pas être vide" which is incorrect, coz 'First name' in French is 'Prénom', hence it should be "Prénom ne peut pas être vide" Please can someone suggest a way of achieving the desired result.

• Accessing a module's action rendered output

  - by Flavius

  Hi. I'm writing an "Account" module which should take care of everything about accounts: registration, login/logout, user administration, password recovery, account activation, etc. So I thought it would be best to reuse whatever the module's DefaultController::actionRegister() generates to show on the main page. So my question is: how to create a new "sub request" (similar to CController::forward()) from any controller (either SiteController, read: from views/layouts/main.php, or another controller, eventually of another submodule) to a given module/controller/action? I've tried with $this-forward() from within my application layout without success: it shows a blank page, no error whatsoever. Thanks

• serving files using django - is this a security vulnerability

  - by Tom Tom

  I'm using the following code to serve uploaded files from a login secured view in a django app. Do you think that there is a security vulnerability in this code? I'm a bit concerned about that the user could place arbitrary strings in the url after the upload/ and this is directly mapped to the local filesystem. Actually I don't think that it is a vulnerability issue, since the access to the filesystem is restricted to the files in the folder defined with the UPLOAD_LOCATION setting. UPLOAD_LOCATION = is set to a not publicly available folder on the webserver url(r'^upload/(?P<file_url>[/,.,\s,_,\-,\w]+)', 'aeon_infrastructure.views.serve_upload_files', name='project_detail'), @login_required def serve_upload_files(request, file_url): import os.path import mimetypes mimetypes.init() try: file_path = settings.UPLOAD_LOCATION + '/' + file_url fsock = open(file_path,"r") file_name = os.path.basename(file_path) file_size = os.path.getsize(file_path) print "file size is: " + str(file_size) mime_type_guess = mimetypes.guess_type(file_name) if mime_type_guess is not None: response = HttpResponse(fsock, mimetype=mime_type_guess[0]) response['Content-Disposition'] = 'attachment; filename=' + file_name #response.write(file) except IOError: response = HttpResponseNotFound() return response

• How to organize asp.net mvc project (using entity framework) and a corresponding database project?

  - by Bernie

  I recently switched to vs2010 and am experimenting with asp.net MVC2. I am building a simple website and use the entity framework to design the data model. From the .edmx file, I generate the database tables. After a few iterations, I decided that it would be nice to have version control of the database schema as well, and therefore I added a database project into which I imported the script that is generated from the datamodel. As a result, I have to generate the sql every time that I change the model and redo the import. The database project automatically updates the database. Although the manual steps to generate the sql and the import are annoying, this works pretty well, until I wanted to add the standard tables for user accounts/authorization etc. I can use the framework tools to add the necessary tables, views etc. to the database, but as I do not want to have them in the .edmx model I end up with a third manual step. Is anybody facing similar issues?

• How to handle similar items in rails MVC?

  - by mocker

  I'm working on building a pretty simple site mainly as an exercise in learning more about rails. You can see my rough progress at statific.com. It's working pretty much as I wanted it for keeping track of server information, but now I'd like to expand it to other things, next on the list being firewalls. I can pretty easily duplicate all the models, views, etc.. that I have for my servers. The problem I see with that is that it isn't very DRY since most of the code would look the same, the only difference would be the attributes I have setup for firewalls would be different than for servers. I know in plain ruby this is pretty simple, you can have a 'Product' w/ common attributes ('manufacturer', 'model') and then have children with more specific attributes. Does the same type of concept exist for rails, or am I just over thinking this?

• how to organize javascripts using rails and jquery

  - by VP

  Hi, i'm working in a big and rich rails web application using tons of javascript. I would like to know if anybody has a tip to organize the javascripts. Today i'm generating a new file named controller.js and adding it to my views using content_for. The problem is, some files are becoming big and sometimes, i need a function from one controller in another, so then in the end, i add a products.js to a details controller just to keep DRY. Is that solution good? Any other tip? I think the same pattern can be applied as well to css files?

• Django - transactions in the model?

  - by orokusaki

  Models (disregard typos / minor syntax issues. It's just pseudo-code): class SecretModel(models.Model): some_unique_field = models.CharField(max_length=25, unique=True) # Notice this is unique. class MyModel(models.Model): secret_model = models.OneToOneField(SecretModel, editable=False) # Not in the form spam = models.CharField(max_length=15) foo = models.IntegerField() def clean(self): SecretModel.objects.create(some_unique_field=self.spam) Now if I go do this: MyModel.objects.create(spam='john', foo='OOPS') # Obviously foo won't take "OOPS" as it's an IntegerField. #.... ERROR HERE MyModel.objects.create(spam='john', foo=5) # So I try again here. #... IntegrityError because SecretModel with some_unique_field = 'john' already exists. I understand that I could put this into a view with a request transaction around it, but I want this to work in the Admin, and via an API, etc. Not just with forms, or views. How is it possible?

• Sql server indexed view

  - by Jose

  OK, I'm confused about sql server indexed views(using 2008) I've got an indexed view called AssignmentDetail when I look at the execution plan for select * from AssignmentDetail it shows the execution plan of all the underlying indexes of all the other tables that the indexed view is supposed to abstract away. I would think that the execution plan woul simply be an clustered index scan of PK_AssignmentDetail(the name of the clustered index for my view) but it doesn't. There seems to be no performance gain with this indexed view what am I supposed to do? Should I also create a non-clustered index with all of the columns so that it doesn't have to hit all the other indexes? Any insight would be greatly appreciated

• rails: date type and GetDate

  - by cbrulak

  This is a follow up to this question: http://stackoverflow.com/questions/2930256/unique-responses-rails-gem I'm going to create an index based on the user id, url and a date type. I want date type (not datetime type) because I want the day, the 24 hour day to be part of the index to avoid duplication of page views counts on the same day. In other words: A view only counts once in a day by a visitor. I also want the default value of that column (viewdate) to be the function GETDATE(). This is what I have in my migration: execute "ALTER TABLEpage_viewsADD COLUMN viewdate datetime DEFAULTGETDATE()`" But the value viewdate is always empty. What am I missing? (as an aside, any other suggestions for accomplishing this goal?)

• iOS6 MKMapView using a ton of memory, to the point of crashing the app, anyone else notice this?

  - by Jeremy Fox

  Has anyone else, who's using maps in their iOS 6 apps, noticing extremely high memory use to the point of receiving memory warnings over and over to the point of crashing the app? I've ran the app through instruments and I'm not seeing any leaks and until the map view is created the app consistently runs at around ~3mb Live Bytes. Once the map is created and the tiles are downloaded the Live Bytes jumps up to ~13mb Live Bytes. Then as I move the map around and zoom in and out the Live Bytes continuos to climb until the app crashes at around ~40mb Live Bytes. This is on an iPhone 4 by the way. On an iPod touch it crashes even earlier. I am reusing annotation views properly and nothing is leaking. Is anyone else seeing this same high memory usage with the new iOS 6 maps? Also, does anyone have a solution?

• UIViewController prevent view from unloading

  - by Ican Zilb

  When my iPhone app receives a Memory warning the views of UIViewControllers that are not currently visible get unloaded. In one particular controller unloading the view and the outlets is rather fatal. I'm looking for a way to prevent this view from being unloaded. I find this behavior rather stupid - I have a cache mechanism, so when a memory warning comes - I unload myself tons of data and I free enough memory, but I definitely need this view untouched. I see UIViewController has a method 'unloadViewIfReloadable', which gets called when the Memory Warning comes. Does anybody know how to tell Cocoa Touch that my view is not reloadable? Any other suggestions how to prevent my view from being unloaded on Memory Warning? Thanks in advance

• UISplitViewController: how to get toolbar if details controller is UITableView?

  - by Krumelur

  Hi, I checked out Apple's example on how to exchange detail views in the UISplitViewController (http://developer.apple.com/library/ios/#samplecode/MultipleDetailViews/Introduction/Intro.html#//apple_ref/doc/uid/DTS40009775) and it seems that they put the UIToolbar in every detail controller. Then, if the device is rotated, they hide the toolbar or show it and add a popover button which will show the root controller. I'd like to adopt this pattern to show my root controller in a popover using a button in the toolbar, but unfortunately, my detail controllers are all UITableViewControllers and they do not allow adding other UI elements than a table view. So how do I deal with that? Is there an example around? René

• How to segue modal without losing tab bar controller

  - by Arian

  Okay, so I want to be able to have a TabBar Controller with two Tabs (like the template in Xcode), but inside the Second tab, I want to have a button that takes the view to a Third View Controller. I want the Third View Controller to have a back button to the Second Tab, I don't want the Third View to retain the TabBar, but when I go back to the Second Tab I want the TabBar to return. So this is what I actually did, and it doesn't work. I put a button in 2nd view and 3rd view, and I control clicked and dragged to the respective views, and clicked modal. Everything works, except when I go back to the 2nd view I lose the tab bar. Pictures of what I am talking about: http://s13.postimage.org/78gqghflj/Screen_Shot_2012_07_09_at_2_03_41_PM.png http://s16.postimage.org/gdwus4w6t/i_OS_Simulator_Screen_shot_Jul_9_2012_2_02_50_PM.png http://s10.postimage.org/5uq3ste7d/i_OS_Simulator_Screen_shot_Jul_9_2012_2_02_57_PM.png http://s8.postimage.org/gpmsx959x/i_OS_Simulator_Screen_shot_Jul_9_2012_2_03_54_PM.png

• Any MVVM frameworks work well with NavigationWindows?

  - by Will

  I'd like to "throw away" the current version of a WPF application and move version 2 to a stable MVVM framework. The main concern I'm having is that I don't see much talk about MVVM frameworks and navigation (i.e., NavigationWindows and Frames). My current app relies heavily on Pages to present views to the user. I would prefer to keep it this way. I'd rather not change everything to UserControls and rely on DataTemplates to switch out the view I need to present. Are there any MVVM frameworks that: Work well with NavigationWindows and Pages Provide ViewModels adequate access to the navigation process Provide the ability to change navigation in response to security-related events (e.g., redirect to login Page after logout)

• How do you implement paging in ASP.NET MVC?

  - by Kevin Pang

  Currently, I'm using a strategy found on many blog posts. Basically, the URL contains the page number (e.g. /Users/List/5 will give you the users on page 5 of your paged list of users). However, I'm not running into a situation where one page must list two separate paged lists. How do I go about doing this using ASP.NET MVC? Do I simply provide two url parameters (e.g. /Users/List?page1=1&page2=2)? Is there a better way by using partial views?

• Upgrading a SharePoint list instance that was deployed via feature

  - by Goldmember

  I'm curious how others address this issue. Using VSEWSS 1.3, I have created a site content type, a list definition (w event receivers), and a list instance. All of them are in the same WSP solution and each is activated individually via features. Now let's assume that all the features have been activated for some time, and the list instance contains a number of items (that can't be deleted). Now suppose I need to make a change to the schema.xml (inject some javascript, modify views, whatever) of the list. Is it even possible to "upgrade" the schema of the existing list instance? Otherwise I would think I'm stuck creating a new instance and copying items over.
